IMO Everything in our world is natural, the result of natural causes that, from a cosmic perspective, make total sense. From that perspective there is no good/bad duality—everything is good.

Is "criminal law" natural? Is societal prohibition of individual behaviors natural?

I mean, if there was no need for a society to prohibit particular behaviors by an individual, then there is no need for criminal law, and without criminal law, there is no crime.

Whether crime is natural is a misleading question, that places individuals apart from the social context.

Crime is inevitable. The better question is why does a society need to prohibit certain individual behaviors, and what is the process in which it selects what behaviors to prohibit.

I hate to say it, bu to some extent it probably is.

We evolved competition for resources, and one survival strategy woudl be to commit "crimes" as a way of reducing competition.

The challenge i sto differentiate between crimes committed without necessity from those that are committed with necessity (such as stealign a loag of bread to feed one's family ala "Les Miserables" ).

Currently, in the U.S. at let, we punish those who are poorest and who lack resources the most, when ti coudl be argued that they are most subject to survival instincts that cause them to commit crimes, while those who are wealthy, seldom are prosecuted for the crimes they commit, unless they commit crimes against other wealthy people.

In my opinion, we have the distribution of criminal punishments totally backwards.
